Minority Influence, Divergent Thinking and Detection of Correct Solutions

In many applied settings involving influence processes in small groups, the interest is in how such processes aid or hinder effective decision making and problem solving. In a recent formulation, Nemeth (1986) argued that exposure to opposing views emanating from a minority leads to divergent thinking, a process that involves a consideration of the problem from varying viewpoints. On balance, such influence would aid performance. Exposure to opposing majority viewpoints leads to convergent thought where S s presumably concentrate on the proposed viewpoint to the exclusion of other considerations. On balance, this form of influence tends not to aid performance and may prove to be an impediment. In the present study, these hypotheses were tested in the context of anagram solutions. Results showed that subjects exposed to the minority viewpoint found more correct words and they achieved this superior performance by a usage of all possible strategies. Subjects exposed to the majority viewpoint initially used the strategy suggested by the majority to the detriment of other strategies and, in general, performed at the level of control subjects. These results are discussed in terms of potential contributions made by exposure to dissenting minority viewpoints in small group decision-making settings such as trial by jury and in society at large.     

Linguistic analysis of a bilingual stutterer

The ultimate test of the adequacy of linguistic models of fluency breakdown is the degree to which they may account for patterns of dysfluency in the speech of a stutterer who is fluent in more than one language. We present the case of an adult bilingual stutterer (Spanish-English), whose spontaneous language in both Spanish and English was structurally analyzed to assess the relationships of phonological and syntactic structure to the frequency and location of fluency breakdown. Our findings suggest that syntax is probably a greater determinant of stuttered moments than is phonology. Additionally, similarities and differences between English and Spanish sentence structure were associated with similarities and differences in the loci of dysfluencies across the two languages. The need for crosslinguistic research utilizing monolingual and bilingual speakers of languages other than English is emphasized.     

Characteristics of Suicidality Among Adolescents

The identification of high-risk adolescent suicide attempters in a population of depressed and suicidal adolescents is of crucial importance. This retrospective study examined characteristics of suicidality (recent and lifetime, active and passive) and psychopathology (depression, aggression, impulsivity, stressful life events, SCL-90 dimensions) among four groups of depressed adolescent outpatients: (1) suicide attempters who required medical treatment (n = 84), (2) suicide attempters who did not require medical treatment (n = 57), (3) suicidal ideators who had never made a suicide attempt (n = 40), and (4) nonsuicidal patients (n = 44). Results indicate that the nonsuicidal group could be differentiated from the three suicidal groups on the basis of suicidality and psychopathology, and that the three suicidal groups could be differentiated from one another on the basis of suicidality but not psychopathology. These findings are discussed in terms of the usefulness of certain self-report measures of suicidality for identifying suicidal adolescents and for differentiating among them. Furthermore, the findings suggest that psychopathological factors do not determine which suicidal adolescents make a medically dangerous suicide attempt and which do not.     

Internalizing and Externalizing Behaviors Share a Common Predictor: the Effects of Early Maladaptive Schemas Are Mediated by Coping Responses and Schema Modes

We investigated the relationships of adolescents’ internalizing and externalizing behaviors with their early maladaptive schemas (EMS), coping responses, and schema modes. We focused on EMS related to experiences of disconnection and rejection that comprise vulnerable emotions, such as shame, mistrust, deprivation, abandonment, and isolation/alienation. This cross-sectional study included a total of 699 adolescents (combined clinical and non-referred sample) who were 11 to 18 years old (M?=?14.6; SD?=?1.6), and of which 45% was male. All participants completed self-report questionnaires on EMS, coping responses, schema modes, and behavior problems. We aimed to clarify the relationships between these variables by testing mediation, moderation, and moderated mediation models. In general, coping responses functioned as mediators rather than moderators in the relationships between EMS and schema modes. Furthermore, EMS regarding experiences of disconnection and rejection were related to both internalizing and externalizing behavior problems, and coping responses and schema modes mediated these effects. In conclusion, although adolescent internalizing and externalizing behavior problems manifest quite differently, they seem related to the same EMS.     

Deconstructing trait anxiety: a network perspective

Background and objectives: For decades, the dominant paradigm in trait anxiety research has regarded the construct as signifying the underlying cause of the thoughts, feelings, and behaviors that supposedly reflect its presence. Recently, a network theory of personality has appeared. According to this perspective, trait anxiety is a formative construct emerging from interactions among its constitutive features (e.g., thought, feelings, behaviors); it is not a latent cause of these features.

Design: In this study, we characterized trait anxiety as a network system of interacting elements.

Methods: To do so, we estimated a graphical gaussian model via the computation of a regularized partial correlation network in an unselected sample (N?=?611). We also implemented modularity-based community detection analysis to test whether the features of trait anxiety cohere as a single network system.

Results: We find that trait anxiety can indeed be conceptualized as a single, coherent network system of interacting elements.

Conclusions: This radically new approach to visualizing trait anxiety may offer an especially informative view of the interplay between its constitutive features. As prior research has implicated trait anxiety as a risk factor for the development of anxiety-related psychopathology, our findings also set the scene for novel research directions.     

Validation of a Self-Concept Scale for Lynch Syndrome in Different Nationalities

Learning about hereditary cancer may influence an individual’s self-concept, which otherwise represents a complex but stable cognitive structure. Recently, a 20-statement self-concept scale, with subscales related to stigma-vulnerability and bowel symptom-related anxiety, was developed for Lynch syndrome. We compared the performance of this scale in 591 mutation carriers from Denmark, Sweden and Canada. Principal component analysis identified two sets of linked statements—the first related to feeling different, isolated and labeled, and the second to concern and worry about bowel changes. The scale performed consistently in the three countries. Minor differences were identified, with guilt about passing on a defective gene and feelings of losing one’s privacy being more pronounced among Canadians, whereas Danes more often expressed worries about cancer. Validation of the Lynch syndrome self-concept scale supports its basic structure, identifies dependence between the statements in the subscales and demonstrates its applicability in different Western populations.
